management of testicular torsion
- possible orchidectomy + bilateral fixation | - surgery to expose and untwist the testis
33
what is benign prostatic hyperplasia
- enlargement of the prostate gland due to an increase in cell number
34
pathology of BPH
- increased levels of dihydrotestosterone in prostate (androgen) - increased oestrogen levels in blood induce androgen receptors in prostate tissue and stimulate hyperplasia

36
differential diagnoses of BPH
- overactive bladder, prostatitis, prostate cancer, UTI
37
investigations for BPH

47
investigations for urothelial carcinoma (bladder cancer)
- urine cytology - IVU - cystoscopy and biopsy - CT/ MRI
48
management of urothelial carcinoma (bladder cancer)
- Tis/Ta/T1 (80% of patients) = transurethral cystoscopy/resection of bladder tumour - T2-3 = radical cystectomy (radiotherapy if need to preserve the bladder) - T4 = palliative chemo/radiotherapy, chronic catheterisation and urinary diversions
49
what is prostate carcinoma
malignant epithelial tumour arising in the prostate
50
pathology of prostate cancer
- arise from precursor lesion (prostatic intraepithelial neoplasia) with neoplastic transformation of the epithelium lining of the prostatic ducts and acini. - mutations in a number of genes
51
clinical manifestations of prostate cancer
- asymptomatic - LUTS - symptoms of metastatic disease
52
investigations for prostate cancer
- often diagnosed through needle biopsy to investigate raised serum PSA - DRE = hard, irregular prostate - increased PSA levels - biopsy

tumour staging of testicular tumours (1-4)
1. no evidence of metastasis 2. infradiaphragmatic node involvement 3. supradiaphragmatic node involvement 4. lung involvement (haematogenous spread)
59
management of testicular tumours
- radical orchidectomy - seminomas are very radiosensitive - chemo = teratoma - radiotherapy = seminoma
60
what is urolithiasis - urinary tract calculi (nephrolithiasis)
- formation of stony concretions in the bladder or urinary tract
61
pathology of urolithiasis
- calculi form leading to blockage and abrasing structures. | - renal stones = crystal aggregates, form in collecting ducts and deposit anywhere from renal pelvis to urethra
62
where are renal stones classically deposited (3)
1. pelviureteric junction 2. pelvic brim 3. vesicoureteric junction
63
risk factors for renal stones/ urolithiasis
- high protein/ salt intake - male, white - obesity - dehydration - meds = antacids, carbonic anhydrase inhibitor - crystal urea - increase in urinary solutes (calcium, uric acid, oxalate, sodium) and a decrease in stone inhibitors (citrate, magnesium)
64
what can renal stones be formed from
- calcium oxalate/ calcium phosphate (hyperparathyroidism, excess dietary calcium, primary renal disease) - magnesium ammonium phosphate - uric acid (hyperuricaemia, dehydration) - struvite (chronic UTI) - cystine stones
65
what are urinary calculi
- renal stones | - crystal aggregates which form in the renal collecting ducts and become deposited in the urinary tract
66
what are triple stones
- result of infections (eg proteus) that produce the enzyme urease which splits urea to ammonia
67
presentation of renal stones
- fever, vomiting, flank pain - most asymptomatic - stones causing obstruction lead to hydronephritis (obstruction + dilation of renal pelvis causing lasting damage) - larger stones tend to remain confined to the kidney - smaller stones tend to pass into ureter and and become impacted causing ureteric colic - infection, haematuria, proteinuria, sterile pyuria
68
where is pain felt for obstruction of the kidney, mid-ureter, lower ureter and bladder/urethra?
- kidney = felt in loin - mid-ureter = mimic appendicitis - lower ureter = bladder irritability and pain in scrotum, penile tip or labia majora
69
investigations for renal stones
CT = gold standard - Xray to detect kidney stones - urine dipstick = blood - 24h urine sample for stone biochemistry - US = hydronephrosis
70
acute management of renal stones/urolithiasis
- NSAIDs for pain - antiemetics for vomiting and nausea - allow stones <5mm to pass spontaneously - IV fluids
71
surgical management of renal stones/ urolithiasis
- percutaneous nephrostomy (drain urine straight from kidney = symptom relief) - ureteric stent - percutaneous nephrolithotomy = remove stone from the kidney by small puncture of skin - endoscopic/open surgery to break down stone - extracorporeal shock wave lithotripsy = uses shock waves to break down stones so fragments can be passed
72
prevention of renal stones
- overhydration - low salt diet - normal dairy intake - healthy protein intake - reduce BMI - active lifestyle
73
lower urinary tract infections
- cystitis - prostatitis - epididymitis/ orchitis - urethritis
74
upper urinary tract infections
pyelonephritis
75
classification of urinary tract infections
- asymptomatic bacteriuria - uncomplicated (normal renal structure and function) - complicated (structural/ functional abnormality)
76
what is the main pathogen that causes UTI
Escherichia coli
77
why are omen more susceptible to UTI
shorter urethra so closer proximity to anus
78
presentation of cystitis (bladder infection)
- frequency, urgency, dysuria, haematuria, suprapubic pain
79
what is the presentation of ascending spread to the kidneys (acute pyelonephritis)
- more severe | - fever, rigors, vomiting, loin pain
80
diagnosis of UTI
- urinalysis = leucocytes or nitrates = quick screening test - look for protein, blood, pH, ketones, glucose, leucocytes an nitrates - microscopy = WBCs, RBCs, casts and bacteria - microbiological culture (midstream specimen)
81
management of uncomplicated UTI
- Abx for 3 days | - if fails then culture urine and treat according to Abx sensitivity
82
management of UTI in men
- lower UTI with 7 day Abx course | - if prostatitis then give a course of ciprofloxacin (able to penetrate prostatic fluid)
83
management of complicated UTI
7day Abx
84
management of UTI in pregnant women
- asymptomatic bacteriuria should be confirmed on a second sample - Abx
85

95
what is urethritis
inflammation of the urethra
96
pathology of urethritis
